High-Precision Simulations of the Parity Conserving Directed Percolation Universality Class in 1+1 Dimensions
Peter Grassberger
Next to the directed percolation (DP) universality class, parity conserving directed percolation (pcDP; also called parity conserving branching annihilating random walks, pcBARW) i…

Extreme-value statistics and super-universality in critical percolation?
Mohadeseh Feshanjerdi, Peter Grassberger
Recently, the number of non-standard percolation models has proliferated. In all these models, there exists a phase transition at which long range connectivity is established, if l…

On three papers by Jurgens \& Crutchfield, and on the basic structure of "computational mechanics"
Peter Grassberger
In a recent paper, Jurgens and Crutchfield [Phys. Rev. E {\bf 104}, 064107 (2021), called ``paper III" in the following] computed what they called the ``ambiguity rate" of hidden M…
